BackgroundsIntracranial post-operative re-haemorrhage is an important complication in patients with hypertensive intracerebral haemorrhage ICH. The purpose of the present study was to determine the value of the computed tomography CT blend sign in predicting post-operative re-haemorrhage in patients with ICH.

MethodsA total of 126 patients with ICH were included in the present study. All the patients underwent standard stereotactic minimally invasive surgeryMIS to remove the ICH within 24 h following admission. There were 41 patients with a blend sign on initial CT and 85 patients without a blend sign on the initial CT. Multivariable logistic regression analyses were performed to assess the relationship between the presence of the blend sign on the non-enhanced admission CT scan and post-operative re-haemorrhage.

ResultsPost-operative re-haemorrhage occurred in 24 of the 41 patients with the blend sign, and in 9 of the 85 patients without the blend sign. The incidence of re-haemorrhage was significantly different between the groups. The multivariate logistic regression analysis demonstrated that the initial Glasgow coma scale score p = 0.002 and blend sign P ConclusionsThe presence of the blend sign on the initial CT scan is closely associated with post-operative re-haemorrhage in patients with ICH who undergo stereotactic MIS.
